Insights

Understanding crosstalk in liver cancer signaling is key. This review highlights how epidermal growth factor receptor (EGFR) interactions influence hepatocellular carcinoma (HCC) development and treatment resistance.

Area of Science:

  • Hepatology and Molecular Oncology
  • Cancer Signaling Pathways

Background:

  • Hepatocellular carcinoma (HCC) is a complex cancer with limited treatment options.
  • Targeted therapies for HCC often face resistance due to intricate signaling networks.
  • Interreceptor crosstalk and feedback loops are critical mechanisms driving therapy resistance.

Purpose of the Study:

  • To review the crosstalk between the epidermal growth factor receptor (EGFR) and other signaling pathways in liver cancer.
  • To identify molecular interactions relevant to hepatocarcinogenesis and therapeutic resistance.

Main Methods:

  • Literature review of signaling pathways in hepatocarcinogenesis.
  • Analysis of EGFR transactivation mechanisms and interactions.
  • Focus on crosstalk relevant to liver cancer development and treatment.

Main Results:

  • The epidermal growth factor receptor (EGFR) acts as a central signaling hub in liver cancer.
  • EGFR transactivation occurs via heterologous ligands, kinase activity, and ligand shedding.
  • Crosstalk involving EGFR significantly impacts liver cancer progression and treatment efficacy.

Conclusions:

  • Understanding EGFR crosstalk is crucial for overcoming targeted therapy resistance in HCC.
  • Identifying these interactions can lead to improved therapeutic strategies for liver cancer.
  • Further research into signaling network interactions is vital for advancing HCC treatment.

Mitogens and the Cell Cycle02:38

Mitogens and the Cell Cycle

Mitogens and their receptors play a crucial role in controlling the progression of the cell cycle. However, the loss of mitogenic control over cell division leads to tumor formation. Therefore, mitogens and mitogen receptors play an important role in cancer research. For instance, the epidermal growth factor (EGF) - a type of mitogen and its transmembrane receptor (EGFR), decides the fate of the cell's proliferation. When EGF binds to EGFR, a member of the ErbB family of tyrosine kinase...

Liver Regeneration01:24

Liver Regeneration

The liver is an important organ in vertebrates that plays an essential role in metabolism. It is also responsible for storing and redistributing nutrients such as carbohydrates, fats, and vitamins in the body. Additionally, the liver releases bile salts which are critical for digesting food and eliminating toxic metabolites from the body.
Cells of Liver
The liver comprises four major types of cells— hepatocytes, stellate, Kupffer, and sinusoidal endothelial cells. The hepatocytes are...

mTOR Signaling and Cancer Progression03:03

mTOR Signaling and Cancer Progression

The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...

Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal01:22

Role of Ephrin-Eph Signalling in Intestinal Stem Cell Renewal

Erythropoietin-producing hepatocellular carcinoma receptor (Eph) and its ligand, Eph receptor-interacting protein (Ephrin) were first discovered in the human carcinoma cell line, hence the name. Ephrin-Eph interaction guides cells to reach their appropriate location in adult tissues. They also play an essential role in the immune system by helping in immune cell migration, adhesion, and activation. Based on their structure and function, Eph is divided into two classes — EphA and EphB.

Regulation of Angiogenesis and Blood Supply01:24

Regulation of Angiogenesis and Blood Supply

Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits.  Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...

Enzyme-linked Receptors01:00

Enzyme-linked Receptors

Enzyme-linked receptors are proteins that act as both receptor and enzyme, activating multiple intracellular signals. This is a large group of receptors that include the receptor tyrosine kinase (RTK) family. Many growth factors and hormones bind to and activate the RTKs.
Neurotrophin (NT) receptors are a family of RTKs, including trkA, trkB, and trkC (tropomyosin-related kinase) receptors. TrkA is specific for nerve growth factor (NGF), neurotrophin-6, and neurotrophin-7. TrkB binds...
